I recently acquired the above-mentioned amp. Up until this week, I haven't had much time to play with it. Unfortunately, when I use it with clean settings, I can hear a distorted underlying sound. It's almost like a second signal that comes through. It's even noticeable when dialing in an overdriven tone.

Has anyone else come across this issue before? Any insight/suggestions you can offer would be greatly appreciated.

No, sadly, it was purchased used -- but like new. (Purchased on reverb) It arrived in original packaging with labels and no signs of use. It definitely didn't have the issue the first couple of times I played it.

It's definitely not the guitar or cables. I've tried 6 different guitars with the same result and 4 different cables, all direct.

I'm wondering if it might be a tube problem. I may just have to bite the bullet and pay to have it checked by a professional. Unfortunately, there's a $60 eval cost for the local fender authorized repair location, since I doubt I'll be able to use the warranty. It's a shame considering the amp is basically brand new.

You should've insisted that the seller provide you with the original sales receipt -- those amps are warrantied for five years, provided you can prove the original date on which it was sold.

The warranty is transferable but you *must* provide proof of legitimate ownership.

I am pretty much in the exact same spot: bought a used Bassbreaker 45 in perfect condition, sounded great before I bought it, but once I brought it home there was an odd distorted tone even on top of the clean tone. I'm thinking/hoping it's just a tube issue and having it looked at today or tomorrow. Did you ever figure out what the issue was?

If you cannot remember the last time you got new tubes, you need to get new tubes. If ever you buy a used amp, replacing the tubes should be one of the first things you do.

Utter horseshit!

I've got tubes that were made back when JFK was proclaiming "Ich bin ein Berliner" installed in Fender amps built when LBJ promised not to send American boys halfway around the world to do the job that Vietnamese boys ought to be doing for themselves and those amps sound just as good as the day they were new, thankyewvurrymuch!

Quality bottles = quality service.

It's as simple as that.

you know, Sony tried to give me that line about a Sony Playstation I was trying to RMA. I argued it and won. Either they stand by their product or they don't. I get the thing about date of purchase but not proof of ownership.

I don't change a tube unless there is something wrong with the tube.According to everything I've been taught, consumer grade tubes should last about 10,000 hours.Military spec tubes should bump that to as much as 100,000 hours.To put that in perspective let's say you have (3) two-hour rehearsals per week and (2) four-hour gigs per month.That would be about 32 hours a month or 384 hours a year.In that situation, if you're not abusive with your amp, it would not be unreasonable to expect consumer grade tubes to last 26 years.I've been playing guitar for 50 years and that figure of 26 years seems perfectly reasonable and may even be a little conservative.

A good friend of mine has a Fender Champ 25 which he bought brand new in 1992.It has now been 26 years and his amp, which was his main gigging amp until he bought a small Boogie a few months ago, is working just fine with the original tubes, both pre and power.He's never done a thing to it.

I had a 1972 SFVR in which I was the 2nd owner.The guy who bought it new never once changed a tube.I got it with the original tubes.I changed the rectifier tube and re-biased in order to get a little bit more clean headroom but the rectifier was not faulty.I think the tube was a 5U4 and I put in a 5AR4 or possibly something else.I sold the amp in 2010, still with the factory tubes along with the spare rectifier which I gave the guy who bought it.That's 38 years and the amp was still working flawlessly.

Changing tubes yearly is a colossal waste of money.

Thank you.

When I hear oddball overtones from an amp --- I think main filter caps or speaker VC issues. How old is the amp?

You have another known-good cab, that you can play through. To rule-out speaker issues?
